Numeral I5 designatesxanl electr-iomotor carriedin the lower portion of; the casing I; having a shaft extend--- NumeralI indicates the casing as a, whole,,.

openings throughthe; wall of the enclosure Ia;

Numerals 3 and 3 a, denote hollow. castings se-Q c'uredto oppositewalls,of the enclosure; I a, their interiors, forming extensions; of theopenings .lblli.'The'upper' surfaces of the castings 3 and 3a. are inthe plane of the upper surface of the casting I and are provided withcavites 4 and,

ingfrom said casing; andprovidedwitha pulley I6 at its outer end.Numeral II indicates a shaft at their inner ends to oscillate about thesame pivots-as the cam-leversi l and 22 and at their outer ends arepivoted to: the diaphragm pull rods: I3i-and I3'az Numeral 25 indicatesrods extending-- severally betweentheconstituent links; of each pair oflinks 23-24 in the lines of travel of the outer arm of the adjacentcam-levers 2I or 22. Numeral 26 indicates pressure springs interposedbetween the castings 33a and the outer ends of the cam-levers 2| and 22and acting to yieldingly holdl the inner ends or said levers against theperiphery of thecams 20.

When the motor I5 is set in motion the shaft I1 and cam 20 are rotatedoscillating the camlevers 2i and 22, which on the downward motion oftheir outer arms engage cross rods and press the outer ends of the links23 and 24 downward which carry with them the diaphragm rods l3-i 3a, andwhich are returned by the resilience A of the springs. i4 and I la, onthe upward stroke thus forming a Pump. Should the pressure above thediaphragm, 88a, be greater than the pressure of the springs l4l4a, thediaphragm would not rise with the arm of the cam-lever iii-22, but thearm of the lever would move out of contact with the cross-rod 25, asshown in Figure 5. Thus by adjusting the tension of a spring iii-A la bymeans of a plug 'I1a the pressure delivered can be accurately andcertainly graduated.

There is a nozzle 28 formed to receive a rubber tube at the end of eachof the inlet and outlet passages of said pumps. Numeral 29 denotes a ipeconnecting an outlet passage of one pump with the intake passage of theother of said pumps, and Eli-3i) indicates three-way cocks forcontrolling the passage of. fluid from and to said pumps.

A vacuum gage 3| communicates with the suction end of one of said pumpsthat may be connected to the intake of the other of said pumps.

In the modification shown in Figures 9 and 10,

the circular cam 29 is surrounded with eccentric straps 32 and 32a, fromwhich extend eccentric rods 33 and which pivotally engage the bifurcatedinner ends of the levers 2m and 22a: corresponding to the lever arms 2!and 22 of the construction shown in Figures 1 and 4.

The two pumps may be used singly or they may be used in series ashereinafter described.

In Figures 2 and 3 the port of the intake valve l I of the right handpump is connected by a rubber tubing t l with a receiving jar 35, tocreate a vacuum therein to withdraw fluid from the cavities of a bodythrough the trocar or tube 36, the operation being called aspirating.

The discharge port of said pump is then open to the atmosphere as shownat 28a, see Figure 3.

In Figure 2 the left hand pump has a rubber tube 3'! connected with theport of the discharge tube 12a which terminates in the injection needle38 and which I prefer to have open at its end as shown at (it, seeFigure 8.

Numeral 40 denotes a rubber tube connected with the port of the intakevalve Ila, and this may be connected by branches 40a and 401) withsupply receptacles ll and 42 and each branch may be provided with ashut-off cock 43, so that the operator can employ the material in eitherreceptacle at will.

The two pumps may be used simultaneously, one pump for injecting theembalming fluid into the body through the arterial system, therebyforcing the blood from the body through the veins by way of a drainagetube inserted in the veins, while the other pump is aspirating thecavities of the bodyor the two pumps may be used to inject fluid intotwo bodies at the same timeor one pump may be shut off, withoutinterfering with the operation of the other pump.

Should a greater pressure he required than is furnished by a single pumpthe cooks -30 are manipulated to close the outlet passage of the righthand pump to the outer air and the connection of the left hand pump withthe intake passage at Ila to which the tube is attached, and to connectthe port of the discharge valve l2 of the right hand pump with the portof the intake valve i la of the left hand pump through the pipe 29. Thepumps will then act in series to deliver the sum of the pressures of thepumps, in this case, the tube must be connected to the port of valve II, instead of Ila.

By the use of hydrostatic pressure as provided by the present inventionthe embalmer has at hand a more efficient method of circulating theembalming fluid throughout the arteries, capillaries, and veins of thebody by an even continuous flow of low pressure pulsations, which may bebelow the normal'heart pressure but which, in any event, is such as maybe used without danger of rupturing the blood vessels. The pulsationsdeveloped by the diaphragm pumps are little hammer like blows that forcethe embalming fluid through congested areas in the arteries,

capillaries, and veins of the body where the blood is thick and oftencongealed and are like the pulsations of the heart in life that forcesthe blood to remote parts of the body.

While the apparatus is also adapted for air the latter requires morepressure to do the same work with more danger of distensions and facialdis-' tortions-the bane of the embalmer. The apparatus is portable,quiet and economical in use and while designed particularly forembalming may be used by surgeons, dentists, or artists for use inconnection with the air brush, or any other use where low pressure orvacuum may be applied, such as circulating liquids or transferring samefrom one container to another by either of three ways; vacuum, pressure,or forcing same direct through the pumps.

What I claim is:

Apparatus for use in anatomical injection and aspiration, comprising aunit including tw pump members each having a suction port and a pressureport; means common to both pump members effective for continuousalternating actuation of each pump member; a conduit connecting thesuction port of one pump member and the pressure port of the other pumpmember; valve regulated means connecting said pump members to aninjecting liquid reservoir and to an aspirating receptacle whereby saidapparatus may be selectively controlled so that one of said pump membersmay inject while the other aspirates, or so that both pump members maybe used concurrently for injection on one body or on two separatebodies.
